mcb: Added bar descriptor support for non PCI bus MCB carrier

2016-08-31T11:16:24+00:00

Added support for the bar descriptor. This type is used for FPGAs
connect to the LPC or to a non PCI bus.

The Bar descriptor could have a maximum of 6 BARs. Each of the
devices within the FPGA could be mapped to a different BAR.
The BAR descriptor is comparable to the PCI header.

mcb: Fixed bar number assignment for the gdd

2016-05-03T22:52:28+00:00

The bar number is found in reg2 within the gdd. Therefore
we need to change the assigment from reg1 to reg2 which
is the correct location.

mcb: export bus information via sysfs

2016-05-03T22:07:35+00:00

Export information about the bus stored in the FPGA's header to userspace via
sysfs, instead of hiding it in pr_debug()s from everyone.

drivers: mcb: fix memory leak in chameleon_parse_cells() error path

2014-04-16T19:28:47+00:00

chameleon_parse_cells() bails out if chameleon descriptor type is
invalid but does not free the storage 'header' points to.

drivers: Introduce MEN Chameleon Bus

2014-02-28T23:36:37+00:00

The MCB (MEN Chameleon Bus) is a Bus specific to MEN Mikroelektronik
FPGA based devices. It is used to identify MCB based IP-Cores within
an FPGA and provide the necessary framework for instantiating drivers
for these devices.
